Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed August 24, 1914. Serial No. 858,218.

To all whom it may concern:

Be it known that I, THOMAS M. DANIELS, a citizen of the United States, and a resident of Chicago, in the county of Cook and v State of Illinois, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification.

My invention relates to railways, and the object thereof is to provide a tie for the tracks which not only positively maintains the tracks in relationship with each other, but which also support the tracks in a yielding or resilient manner.

A further object is to adapt said ties for use in connection with wood buffers, and also for use in connection with concrete, without altering the principles of the 1nvention; and further objects are to provide such ties which are positive in results, practically immune from rail displacement, readily installed and removed, and comparatively inexpensive.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in whlch the separate parts are designated by the same reference characters in each of the views, and in which Figure 1 is a side elevation of one form of my tie, partly in section; Fig. 2 is a plan view thereof, with certain parts removed; Fig. 3 is a view of one end of a modification, not all of the parts being shown; Fig. 4 is aside View of the form shown in plan in Fig. 3; Fig. 5 is a side elevation of the tie as employed with concrete; Fig. 6 is a plan view thereof, partly in section; Fig. 7

is a side view of the main or body portion of the tie shown in Fig. 5, detached; Fig. 8 is a bottom plan view thereof; and Fig. 9 is a plan view of the skeleton employed in making the concrete foundation for the tie. In Figs. 1 and 2, I have illustrated one form of my invention, comprising a base 10 provided with four housing cups 11 for coil-springs 12 arranged in pairs, one pair being beneath each rail, and said base is also provided with a pocket 14, between the cups of each pair, and in each of which is arranged a block 15, of wood or other suitable material, directly beneath each rail.

Above the base 10 is a stretcher 16, comprising a bar 17 in the axial planes of corresponding cups of each pair of cups, and which stretcher carries an inverted cylindrical cup 18 telescoped over the correspondmg base cup 11, and slidable vertically thereon, the corresponding spring 12 supporting the several ends of the two stretchers of each tie, and rail clamps 19 are detachably held, by means of bolts 20, on the upper side of the stretcher 16, these being removed from Fig. 2, but one being clearly shown in Fig. 1, and it will be seen that these clamps prevent movement of the rails toward each other. The stretcher 16 is also provided with an upwardly and outwardly directed arm 21, at each end thereof, of such length as to bear against the fish-plate of the tracks in the positions of rail joints, and

I provide an extension 22 for use between fish-plates, so as to insure a side support for the rails, these extensions being readily removable and held in position in any desired manner.

By reference to Fig. 1 it will be seen that the fit between corresponding cups 11 and 18 is a close one, being in fact air-tight, and I provide a check-valve 23 in the position of each of a plurality of air-vents 24:, one for each set of said cups, and the effect of which is to prevent air from escaping from the said cups when depressed by the weight of a train to form an air-cushion within said cups, but air may pass into said cups freely in the upward movement of the cups 18, and I may, if desired, employ small air-holes 25 to decrease the resisting effect of the air-cushion, or any suitable equivalents for the holes 25.

Secured to the outer side of each of the cups 18 are two sets of two inwardly turned projections 26 jointly forming sockets adapted to receive short, oppositely directed, lugs 27 on corresponding rail clamps 28 which are of such length as to bear against the outer fish-plates of the rails, and an extension 29 is provided for the rail clamps between the fish-plates to insure an external support for the rails; the rail clamps 28 are held in position by means of the lugs thereon, but I also provide small plates 30 for this purpose, one on each side of each rail clamp, and the two held together by means of a bolt 31 passed through the corresponding clamp, and I also provide a clamping plate 32 held in position on each rail clamp by means of a bolt 33 for the outer sides of the rails, and it will thus be seen that the rails are immovably held on the tie.

The tie is shown in Fig. 1 in depressed position by the weight of a train passing thereover, and it will be seen that the coil-springs and the aircushions in the four sets of cups take the weight resiliently, and the parts return to normal position as soon as the train has passed; in the event of any or all of the coil-springs breaking, the rails may settle but only as far as the buffers 15 which then support the load, so that no dangerous settling of the rails can occur.

In Figs. 8 and 4, I have shown a flat spring 34 which may be used in conjunction with the coil springs described, these flat springs being arranged in the positions of the wood buffers referred to, and preferably thereover, and they may be held in position by means of small clamping plates, not shown, or in any other desired manner, the effect of which fiat springs is, obviously, to distribute the load over several resilient supports for the rails.

The construction shown in Figs. 5 to 9, inclusive, is intended for use as a concrete tie, and comprises a base formed of a bar 85 having two members 36 riveted thereto at 37, Fig. 9, said members being channeled as shown at 38 and being provided, each, with two sets of oppositely arranged, vertical, slots 39 adapted to receive the corresponding tongue 40 of two sets thereof on each of two stretchers 41, whereby said stretchers are capable of vertical movement at each end thereof, a coil-spring 42 being arranged beneath each end of each stretcher, within the corresponding channel 38, and held therein by means of locking plates 43, Fig. 6; in this form the concrete is poured around the base formed by the bar 35 and members 36, in a form indicated by dotted lines in Fig. 9, thus producing a reinforced concrete base for the operative parts thereover. The outermost tongues 40 of the two stretchers 41 are each provided with lugs 44, forming pockets similar to those formed by the lugs 26, for engagement with the rail clamps 45 in all respects similar to the rail clamps 28 already described, plates 46 holding the same in position, and clamps 47 and bolts 48 holding the rails in position, in the manner already described, and I also provide wood buffers 49 in this form to take the load of a. train in the event of accident to the coilsprings.

The forms are all similar in the main features of rail positioning and resilient supports therefor, one modification, Figs. 3 and 4, employing a supplemental fiat spring beneath each rail, and the other modification, Figs. 5 to 9 inclusive, disclosing a re-inforced concrete base in place of the cast steel base shown in Figs. 1 to 4 inclusive.

While I have shown these three forms, it will be obvious that other forms thereof may be suggested to meet varying conditions, and, with a reservation to myself of all such changes in and modifications of the forms shown and described, as come within the scope of the following claims, what I claim as new, and desire to secure by Letters latent, is

1. The combination with two rails, of a stretcher for maintaining said rails in position, and an air-cushioning chamber at each end thereof for supporting the same resiliently.

2. The combination with two rails, of a stretcher for maintaining the same in position, an air-cushioning chamber at each end of said stretcher, and a check-valve in said chamber.

3; The combination with two rails, of a stretcher for maintaining the same in position, a base therefor comprising a bar, members thereon arranged beneath each rail, a concrete envelop for said bar and members, resilient supporting means interposed between said base and stretcher, and lllilllS for detachably holding said rails to said stretcher.

4. The combination with two rails, of a base, two stretchers for said rails thereon, resilient supporting means interposed between said base and each end of each stretcher, and a buffer arranged on said base, beneath each rail, and between said stretchers.

5. The combination with two rails, of a base, a stretcher vertically guided thereon, resilient supporting means for said stretcher, said stretcher comprising a central member for spacing said rails, and detachable end members for clamping said rails to said central member.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS MARION DANIELS.
